The complete paper compiles recommendations from a broad range of sources into a single document to aid future intelligent-completion installations and operations. While emphasis is placed on subsea completions, these recommendations can be applied readily to differing well types. Important differences between production wells and injection wells also are addressed.
Introduction
Intelligent-completion interfaces span drilling, completions, facilities, production operations, and subsea-systems-engineering disciplines. Affected system components include the tree and tubing hanger, control system, control fluid, control lines, well fluids, well casing, downhole sensors, feed-through packers, and interval control valves (ICVs). Example diagrams are provided in Appendix B of the complete paper.
While a successful intelligent completion can enhance a well’s value significantly, a failed intelligent completion can severely diminish that value, possibly rendering the well inoperable.
